He uses service inquiry.The form of data is written are as follows: n_tac, n_ci, n_arfcn, n_pci respectively represent n-th of adjacent cell
TAC, CI, EARFCN, pci data can directly inquire TAC, CI information subsequently through EARFCN, PCI information.
It is described that corresponding adjacent cell is carried out forcing resident to include: firstly, central processing module in above-mentioned steps S705
C31 is that priority is arranged in each frequency point number, the priority for the EARFCN value for including in the data packet is set as peak, by other
The priority of frequency point number is set as minimum, and above-mentioned peak is much higher than minimum；Then, resident request is sent in data packet
Target adjacent section corresponding to EARFCN, PCI information；After again, the cell access information of target adjacent section feedback is received, judgement is
No resident success is to start verifying process (be intended to verify it and be resident whether successful adjacent cell is pseudo-base station), if verifying is logical
It crosses and then continues to obtain the scheduling informations such as MIB and SIB1 information from the adjacent cell, otherwise re-start next round resident request, due to
Specified frequency point number (i.e. EARFCN information in data packet) has highest priority, much higher than the priority of other frequency point numbers,
Therefore, when re-starting next round resident request, adjacent cell unit 3 EARFCN, mesh corresponding to PCI information still into data packet
It marks adjacent cell and sends resident request, cause to be resident to other adjacent cells without executing re-selecting cell process；It is asked when repeatedly resident
When asking unsuccessful, the resident condition of adjacent cell is obtained from the broadcast message of target adjacent section and whether judges adjacent cell unit 3
Meet resident condition, when the condition that meets and success can not be resident, adjacent cell unit 3 is believed to the main control unit 1 feedback failure
Breath, when being unsatisfactory for resident condition, adjacent cell unit 3 can not obtain information to the main control unit 1 feedback, and user can be by master control
Unit 1 processed, which obtains feedback information, can contact the failure that technical staff checks and repairs base station if non-fault message, if can not
Information is obtained, technical staff can be used other measuring devices and obtain the adjacent cell that can not obtain information and be manually entered to main control
In the storage unit a14 of unit 1.Since in reality, the professional ability of only a few cell base station is very low, adjacent cell list can not be received
The resident request of member 3, therefore in the above process, default adjacent cell unit 3 meets all adjacent cells and is resident condition, until forcing resident
Whether the just detection adjacent cell unit 3 that fails, which meets resident condition, can promote the persistent district of adjacent cell unit 3 and obtain information
Efficiency.
Preferably, above-mentioned verifying process includes: firstly, whether adjacent cell unit 3 judges in cell access information comprising the
One verify data is, then carries out next layer of verifying, otherwise proves that being resident successful adjacent cell is pseudo-base station, and by the pseudo-base station
Information reporting to main control unit 1；Then, adjacent cell unit 3 generates the second verify data according to first verification data, and will
Second verify data is sent to it and is resident successful adjacent cell；Then, adjacent cell unit 3 receives it to be resident successful adjacent cell anti-
The data of feedback simultaneously judge whether data are consistent with desired value, are, can determine that by verifying, otherwise it is resident successful adjacent cell
It is pseudo-base station that proof, which is resident successful adjacent cell, and by the information reporting of the pseudo-base station to main control unit 1.Using above-mentioned verifying
Mode, between adjacent cell unit 3 and target adjacent section can the respective legitimacy of bi-directional verification, guarantee obtain adjacent cell TAC
